I think this is it. I Quit!
I just wasted the last three days grinding the life out of me in the arena trying to get the 4* Nightcrawler. The only character I love the most and I hoped my 1.7M would be enough, but nope, only ended in the 11% ranking, thus, more useless shards. The one character, ONE, character I wanted the most and I can't get him cause there are just so many other people with higher levels and more time then I have to waste life grinding away all day and night. I stayed up till 6am for two of the three days grinding away, did the best I could between working, sleeping and eating, you know, the necessities of life and still, STILL, couldn't get enough. I'm tired and done! I don't have to time or money to waste on this game any longer. The crystal drop rates are pathetic, the amount of shards needed to get the higher level catalyst crystals and alpha catalysts are insane and impossible to get. The level of points needed to win a arena contest is beyond ridiculous, plus the time needed to achieve 2,3,4 million points in absolutely insane. I don't have time for this nonsense. Someone let me know when the requirements come down to some acceptable level where a casual player can get some enjoyment out of the game.
One character, ONE! That's all I wanted and now I'm out three F* days. Thanks. I QUIT!
